Hello, @JennyKIM,

It seems that the crash originates from Unity native libraries.

Another finding is that, right before the crash stack, there is this line:

09-01 18:50:46.834 24050 24080 W VRWatchDog: SUBMIT-TIMEOUT WARNING: 1161 ms

 

Which might suggest the application was frozen before it crashed.

However, as suggested at the beginning, the crash stack originates from Unity native libraries which means that it is pretty much impossible for us to find the root cause of this crash.
